摘要
利用模元素n在整环Z[ω]中的相伴元将复平面分为六部分,并指定其中一部分为消息的有效域,将RSA密码体制及其数字签名方案推广到了Z[ω]中,并给出了一个实例.在安全性方面,所提出的推广体制比原RSA体制具有一定的优势.
The extended RSA cryptosystem and its signature scheme are proposed in the domain Z[ω] by designating one of the six regions of the plural plane which are divided into by the associated elements of modular number n as the message validity region, and an example is given.
